Application filed April 6, 1917. Serial No. 160,261.

To aZZ whom it may concern:

Be it known that 1, Winning N. Bronn'r'r, a citizen of the United States, residing at Savannah, in the county of Chatham and tats of Georgia, have invented certain new and useful Improvements in Combined Priming and Vaporizing Devices, at which the following is a specification.

My invention relates to a combined priming. and vaporizing device, for use in connection With inte'rnalcomhustion engines,

for feeding a gaseous fuel to the cylinder.

or cylinders thereof.

An iniportant object of the invention is to provide means for holding liquid fuel, such as gasolene or the like, Withdrawing a suitable amount of the liquid fuel and vaporizing or atoniizing the same and mixing it with air, forming a gaseous explosive charge, and introducing this gaseous explosive charge into the cylinder or cylinders of the engine, upon the creation of a vacuum therein, when the engine is cranked.

A further object of the invention is the provision of means for preventing back pressure from the cylinder passinginto the device for forcing therefrom the liquid fuel or the like.

A further object of the invention is to provide means whereb the liquid fuel, as such, is not sprayed into the cylinder of the engine, as such liquid fuel tends to injure the wall or walls of the cylinders by Washing oil the lubricatin oil therefrom.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings formin a part of this specification and in which like numerals are employed to designate like parts throughout the same.

Figure 1 is a central vertical sectional view through a device embodying my invention, I,

Fig. 2 is a plan view of the same,

Fig. 3 is a central vertical lon itudinal section through a second form or the invention,

Fig. 4 is a plan view of the same,

Fig. 5 is a central vertical longitudinal sectional view through a third form of the invention, and,

Fig. 6 is a plan view of the same.

lnFigs. l to 6 inclusive, the nunierallil designates a tubular body portion. or conduit, having a longitudinal bore 11. {it its lower end the tubular body portion 10 is provided with a flange 12, carrying a de pending exteriorly screw-threaded tubular nipplelil, adapted to be screwed into an opening in the head of the cylinder of the internal combustion engine.

Arranged Within the tubular nipple 18 is an upwardly closing check or ball valve 14, adapted to seat upon a shoulder 15 for closing the bore 11, and held against downward displacement by a transverse pin 18, as shown. It is obvious that back pressure seats the valve Li and therefore the back pressure cannot pass into the bore 11.

The tubular body portion 10 is provided with a transverse preferably tapered opening' 17. intersecting the bore 11 and receiv- 7 seat 17 by a compressible coil spring 21, as

shown. The valve 18 is provided with a transverse opening or port 22 adapted for movement into and out of registration with the bore 11. it is thus apparent that the valve is provided for partly or Wholly closing or opening the bore 11.

Secured to the upper end oi thevtubular body portion 10 and preferably formed intcgral therewith is a cup-shaped liquid fuel holding receptacle 23, the upper end of which is open, as shown.

in Figs. 2. and. 2, the numeral 24 designates a vertically arranged air supply pipe, having" its lower end screw-threaded into the upper end 0? the bore 11, as showr. at

lhe air supply pipe extends longitudiuall through the receptacle but has no direct cimunuuication therewith. as its upper end is disposed a substantial. distance above the receptacle. Connected with one side of the air supply pipe 524 is a trench pipe '25, serving, as a siphon, and inning its lower end open. and disposed inthe lower portion oi the receptacle 23 hcasath the level of the liquid fuel therein.

In Figs. 3 and 4. the numeral 26 design tes a vertically arranged air supply pipe having its upper end open and disposed a, substantial distance above the receptacle and this pipe 26 extends through the receptacle; and is screw-threadediuto "the uper end' of the bore 11, as shown at 2?. An u verted lit? approximately tl-sha ed ')i e 28, has one b l W end thereof connected with the pipe 26 near r end, While the upper portion of x is arranged above the receptacle iii its lower intalre end 1s disposed ill tilt, receptacle helovv the liquid level ein.

n 5 and 6, a single approximately *1 29 is provided, its d within the recefotnole l level thereof, Whi e disposed above the threaded thin upper end or the here as shown at 30. if he pipe 29 is agzertured or provided With an opening 31, which is arranged above the receptacle 23 and the level of the liquid therein.

in the operation of the form of apparatus shown in Figs. 1 and 2, when the valve 18 is opened, and the engine is cranked, upon the down stroke of the piston, a vacuum will be created in the cylinder, and air drawn inwardly through the air supply: pipe The air traveling through the pipe 324, in proximity to the discharge end of the branch 'pipe 25 creates a sufficient suction therein, for drawing a proper amount of the l quid fuel from the receptacle This liquid fuel is sprayed into the pipe "24 in the presence of downward "traveling air and becomes thoroughly mined revvith he discharged into cylinder engine,

operation of the form of apparatus in Figs. 3 and l is thoughtto he so .irnilar that no, further explanation thereof s hought necessary.

operation of the form of apparatus saovrn in .a 5 and 6, the suction in the to draw air in tl'irough the suc 1 an" entering the opening Bl. a r entering the opening" 31 creates a suitable suction within the lower portion or free end 29 of the pipe 29, which corresponds to the pipe and may he coniclered as an extension of the pipe 99. and

nrpe 1 'LliiS suction draws up a suilicient amount of iquid fuel which becomes mixed with the air and is fed to the cylinder of the engine. is to he understood that the forms of invention herewith shown and described are to he taken as preferred examples of the same, and that various changes in the shape, size, and arrangements of parts may he resorted to without departing from the spirit of the invention or the scope of the subed clairns.

rlaving thus described my invention, 1 claim:
